"-This invention relates to combination faucets for delivering either hot, cold or warm water through a single nozzle. 7 V A The main object of the invention is to provide ina relatively simple, compact and durable form, a'device for the purpose above designated. r I a I .Another obj ect' is to provide a'combination hot and cold water faucet,- controlled by-a in single handle, the lateral movement ofwhich operates to open or'c'lose the hot and ,cold" water portsin any required degree, and the vertical movement of which operates'to deliver the water through thenozzle. device of the kind described a water channel controlled by-a valve assembly comprising aprimary and a secondary-valve, the secondary valve being adapted to raise" or "lift slightly, inad 2 o Vance of the larger primary valve, whereby 2-2 ofFigure 1;

Figure 3 is a view similar to Figure'l, but

2 taken on a;sightline.,-perpendicular to the sightlineof Figure 1; =.:Figure 4 is a detail valve; I f;-Figure"5 is a detail in plan of: the double acting'port valve... V The' inventioncomprises a. suit-ableshell 'or ca sing-l'iormed with acircularinozzle openn plan of the primary,

nular. washer recess 3 for the reception of a suitable packingjwasher'i-l. The casing 1 is open atthe top side and is formed with later ally disposed hot-and cold water ports 5 and 6 which connect with the laterally spaced water leads or pipes 7 and 8 in conventional manner. c- I The top of the casing is closed acoverplate 9 which is fastened down by means of screws 110 The plate 9 islformed with acen' tral, integral sleeve 11 which projects partlybelow'the'plate 9. The sleeve 11 is'adapted to receive a thimble 12which is rotatably mounted therein with its open end downward. A,cap1l ,'having the handlelugs 15 at the apex thereof andbei'ng formed with a cention ofthe'upper end of the thimble 12, is provided and 'rotatably mounted upon the cover plate 9, withv the socket 16 engaging the thimble 12 as stated. Thethimble 12' is then pinned to the cap l'bymeans of a pin 17 so that thethimble will rotateas the cap isrotated. A suitable operating handle '18 PAT NTJ FF Q 'tral socket-16 at its under side for the recepis pivoted for verticalmovement between the lugs 15 by means of the pin 19.v The handle 18 is extended rearwardly as shown, and to a it is pivotally'pinned at20 for movement in a vertical plane the handlebar .21 which depends at the rear of'the casing 1 and is then bent forwardly and formedointo-a ring 22 disposed immediately under the nozzle opening 2 of thesaid casing.

A cylindricalnozzle 23 is snugly but slidably j ournaled through the nozzle opening 2, its lower end being-passed freely through the ring 22 of the handle bar 21.; The upper I endof the nozzle :23is bridged by a brldge piece 2 1 whichcarries the upwardly project ing valve'lug25; Tlie-lowerfmouthof the nozzle opening 2 is tapered orv flared as shown at 26 to complementarily engage atapered or beveledsealing ring 27 which is fixedly mounted upon 'theflowe'r end of the nozzle 23. This mounting, is accomplished by welding or in any other conventional man-:

ner. Thus upon thevupward' slidinglmovement of the nozzle, the beveledlift ring 27 V enters the flared mouth'26 of the nozzle, and serves as a sealfagainst water under pressure Working down the outer face of the nozzle fromthe inside of the casing 1. A circular primary valve 28 formed atits under side with a bore or seat 29 adapted tosnugly but freely engage the upper end of the nozzle23,

and having a reduced opening '80 formed. through'its upperiside, is mounted in place over 'the'upper end of the nozzle 23 in manlBlc described The valve 28 is countersunk tween the cover plate 9 an'dtlre said spring seats 34 serve to normally hold the valve 28 down to its seat upon the washer 4. A sec ondary valve 36 is adapted t-o seatuponthe washer 31 and close the opening" through 37 extends'from the valve 36 up into the mouth of the thimble 12. A coil spring 38 seated within thethimble 12 normally forces the valve 36 to its seat upon the washer; 31. A circular cam 39 having a valve stem opening 40 cccentrically formed thereth-rough is rigidly affixed at the lower end of the thimble 12 with the opening lO'aligned with the cavity of the thimble, Thus the valve stem 37 may nass freely through the opening 40 up into t e thimble. An oval shaped valve ring or yoke 11 is'slidingly mounted over the cam 39, and supports at either end a valve {l2 adapted to seat against and close the water' ports'5'and 6.. Thearrangement is such that as the cam 39 oscillates or partially rotates under the movementof the connected handle 18, the yoke 11 is projected laterally towards one side or the other of the casing -1', and the assembly is so proportioned that upon such lateral movement either of the ports 5 or 6" will be closed by the valve 42 at that end of the yoke, while the other one of the said ports remains open for the ingress of water into the said casing. Stops 43 are mounted inside'the yoke41 opposite to the valves 42, and a lug 44 upon the periphery of the cam 39 is adapted t'oimpinge against either of these lugs upon the lateral movement of the cam, whereby the said movement of the cam is limited or stopped at the exact point at which either of the valves 42 becomes fully -closed against its opposed water port, 45 or 6; Guid'e' lugs 45' are mounted upon the under face of the cover plate 9 in such position that when the plate 9 is mounted in place upon the casing 1, the

' lugs 15will stand vertically aligned with the lower lugs 33. The valves 42 are slotted upon their upper and lower edges as shown at 46, whereby they are slidably mounted between the said lugs 33 and 15'as clearly shown in Figure 3.

The ring 27 is so positioned upon the lower end of the nozzle 23 that when that nozzle is in its lowermost position the said ring will stand substantially spaced from. the flared n1outh26 of the nozzle opening 2: The valve lug 25 falls just a little short of impinging opened or closed in manner hereinbefore set 1 out, and this water-is then passed out through the nozzle 23 by depressing the outer end of the handle 18. In this operation the nozzle 23 is raisedhy or through the ring 22 striking the ring 27, whereupon the Valve lug '25 immediately strikes the secondary valve 36 and forces that valve upward, thereby adniittingarelatively small flow of Wathe primary valve 28. A round stem or shank ter throughthe' nozzle 23 and relieving to that extent the total of the water pressure upon the upper faces of the; two valves 28 and 36. The'continued upward movement of the'nozzle' 23 then results in the upper endof the nozzleimpinging against the under face of the primary valve 28, whereby that valve is inturnraised and a full flow of water passes through'the nozzle 23.

When the water passing through the cas this, the flared mouth 26 is provided for the opening 2- to coact withthe beveled sealing ring '27, as above stated. It is noted that with the handle 18 in midwayposition, both valves 1 42 shall stand partly open, so that warmwater will be discharged, and, of course,- by varying the relativedegree of closure of the valves, the temperature of the waterican be'regulate'd'to suit.

While I have herein described a preferred embodiment ofmy invention, it is understood that the structural features referred to may be changedin' minor details,"without depart= ing from the spirit'of'my invention as'defined in the appended claims.

Iclaim: r p 1. A combination water faucet, com a suitable casing open at the top and ivin'g laterally disposed hot; and'cold water ports and a lower centrally located nozzle ope ing, a cover plate for the top of .thecasing,
